(B) The hydration of ethyne $(HC \equiv CH)$ in the presence of $HgSO_4$ and $H_2SO_4$ is a classic reaction known as Kucherov's reaction.This reaction proceeds via the formation of an unstable vinyl alcohol (enol) intermediate,which undergoes tautomerization to form a stable carbonyl compound.$HC \equiv CH + H_2O$ $\xrightarrow{HgSO_4 / H_2SO_4} [CH_2=CH-OH]$ $\rightarrow CH_3CHO$ (Acetaldehyde).
